Kingdom Ducks doodles. I eventually decided Dewey should have a little pendant to fill up that blank part of his outfit. I'm thinking it's patterned after the moon icon from Dewey Dew-Night, and maybe connected to the Sphere of Selene. He also gets the Glide ability, for reasons including:
It's basically falling with style, and he's all about both blind-faith leaping and style
He takes after Della when it comes to the skies, and I already decided she has Glide
He's the best at using pixie dust in Neverland. He's good at conjuring happy thoughts regardless of the circumstances, whereas his brothers sometimes falter due to overthinking (Huey) and general pessimism (Louie).
Context for the last doodle is that Huey fell inside his own magic hat but reappeared when Dewey tried to put it on. Wonderland shenanigans.
